I’m trying to figure out when “record” would ever be hyphenated. If it doesn’t fit on one line, just put it on the next, right? No need to do some weird “rec-ord” / “re-cord” hyphenation.
Though I think the main reason would be limited horizontal space, e.g. a table cell or narrow newspaper column.
And I only used "record" as it was the example given to me. I'm sure there are others. Is a good example for how/why counting syllables can be harder than folks think. Well, kind of a good example; since you will get the right count, regardless.
